Civil airmail is one of the fastest growing sources of carbon emissions as people increasingly take to the skies and new technologies have been slow to make remarkable progress. At 285 grammes of CO₂emitted per kilometre (mile) travelled by each passenger, airline industry emissions far exceed those from all other transport, according to the European Environment Agency.

The e-plane—a 62-year-old, six-passenger DHC –2 de Havilland Beaver seaplane improved on with an electric motor—was piloted by Greg McDougall, founder and CEO of Harbour Air. “For me that flight was just like flying a Beaver, but it was a Beaver on electric steroids I actually had to turn off the power button,” he said. McDougall took the plane in a short circle along the Fraser River near Vancouver International Airport in front of around 100 onlookers soon after sunrise.

A. The flying time of e-plane is 15 minutes at most.

B. The fully electric commercial airmail has functioned.
